M on the table 91 of a the charge of ufacturing process be continuous day and night, I propose l of the furnaces.

The entire actuation ofthe (which determines the rate of glass delivery to the forming iiia' chine) and the operation of the pressing ma chine, is operated from a single power shaft I provide a stationary bearing 26 and a movable bearing 2 to carry the furnace. All

lthe operations necessary to move the furnace are provided for by a` shaft 2T driven by a gear Q8 and ratchet arni 29 shown in detail `in Figure :Z and hereafter. described. It is sufficient at this point to Say, that the furnace may be entirely removed by merelyv disconnecting the air and gas pipes in the usual ting the driving link Q9 oil' of its connecting pin on the armfl). The furnace 30 may be of the usual construction of iron framing and the outside easing is as customary; but the entire frame and easing are supported on thetixed trunnions 31 at the front of the furnace, and bearing 32 at the rear of the furnace engaging a movable trunnioned nut 33 riding on a pivoted screw 34, which has a bearing in the frame 25 and is rotated slowly and intermittently by gearing 35 and 36 from the shaft 2T. 'llieinterior construction of the furnace peculiar; the melting pot 37 as seen in Figure 6 is of wedge shape, with vertical sides, so that as the furnace is tipped about its pivoting point, which corresponds with the line of the pouringniouth 38, the glass is always poured from the same level and from cxactly the saine position in the-furnace. That is, the pouring point is' immovable and thc lwhole bod)Y of the glass moves around it as a center. By this means I `ani enabled to drain oil' thc entire charge of glass, leaving no residue to mix with a new charge, which would be very detrimental. The raw niaterial for the glass may be introduced by lifting ofi' the top 39. lt will be observed that the-pot 37 is in a reverberatory chamber formed by the passages 40 and 41, being heated in any convenient way, as by the air and gas burner 42 fed by any convenient i'orm of piping 42,

The pouring of the glass from the furnace 30, accompanied by the slow revolution of shaft 27 and screw 34, is brought about way, and lit .iii

the reciprocating movement of arm 29, which as will he secu in Figures l, 2 and Il, is provided with a dog or ratchet il, moved intern'iittently. and moved any desired distance to regulate the flow of glass, by iii-cans of lining 29a engaging an adjustable wrist pin cl2 set -in a revolving Wheel lil, geared up, as will be obvious from Fig. 2l. with the main. power shaft ll. That is, by attach` mont to acontinually rotatingr element, the eleganti circular rack just described will slowly 'and continuously tip the furnace about its pouring spout as an axis, so as to deliver a continuous stream of glass at the exact rate required. The adjustment is made without stopping the machine. The glass is always under the same conditions of temperature, pressure head, movement, etc., and the entire charge ot' the furnace is used up,

The stream ol' glass protected by the hood fl'sl Hows into the interruptor chamber l5 from which it may be delivered in any de* aired manner to the molds.

Briejv, the operation ol' the apparatus is as foliows- The glass having); been properly mixed and melted in the combined melting and pouring pot 37, it will 'oe understood that the #lass loi's in a continuous or unbroken stream through the spout 38 into the interruptor chamber. Although the screw 23,4 tilting the furnace has an intermittent step by step movement, this is very slow, and the changes of positions are so small that they do not interrupt the continuity of the out-pouring stream.

As stated7 all of the motions of the machine are accomplished from the single power shaft P, and Without anir hand nianipulation. The process may thus lie continued without cessation, since the furnace BO may be removed and. replaced. Among the advantages of my invention are vthe complete emptying of the melting tank, und the uniform pouring therefrom of glass under` absolutely constant conditions.

ils stated, this application is tiled as adivision, its purpose being to @over the construction of a inciting furnace above specin fied.. While to properly explain its operation, certain other features have been illustrated or referred to such other features form no part of the invention to be here V.nace and a source of fuel sugoiA claimed, they the claims in the said original application. or ol other applications tiled as divisons thereof.l

Having thus described. the subieet-matter vof this application what is herein claimed as the invention of rlinooonn C. @Temen (deceased) is:-

l. ln an apparatus for delivering glass.l the combination with a melting furnace olv# oteel to move on a horizontal anis., a heated chamber adjacent to the furnaceand hai# ing a delivery-orifice, and coordinated .means to permit the intermittent flow of Glass from the orifice and to tilt the furnace to deliver glass to the heated chamber at a rate equal to the rate of escape from the orifice to maintain a constant glass level in the chamber.

The combination with means for de livering glass charges comprising conM taiuer for containing heated glass and means for controlling the feed of glass t" ot' supporting frames movable in the container7 a furnace for 'nie mounted in each frame, means for ingr glass from each furnace wir operative relation with the removable connections between a and u source of fuel supply.
